Maggie Witek works on developing new strategies for isolating liquid biopsy markers found in biological fluids (i.e., blood, plasma, saliva, urine) of patients diagnosed with different diseases (i.e., blood and epithelial cancers, stroke, cystic fibrosis). Her work is leading to development of new technologies and methods for isolating biomarkers such as circulating tumor cells, exosomes, and cell-free DNA, and downstream analysis of the molecular cargo originating from these biomarkers. Maggie is conducting seminal work in Precision Medicine which provides more accurate information related to new treatment ideas and focuses on tailored treatment regimens for individual patients. When it comes to treatment of these diseases: one size does not fit all!

Maggie performs her work in the NIH/NIBIB funded Center of BioModular Multiscale Systems for Precision Medicine (CBMM) as an investigator, coordinator of the Center’s collaborative and service projects, and a leader of the training and dissemination activities (, @CBM2Medicine  on Twitter and Facebook).
